Hello,
In the http://bugs.python.org/issue10093 discussion, I proposed to add a
specific warning category for unclosed files. The rationale is that
these warnings will happen in destructors and therefore filtering by
line number and filename doesn't make sense. So a new category would be
useful in order to allow defining specific rules.
Do you think it would go against the moratorium?
As for the category name, I would suggest ResourceWarning if we use it
specifically for resource-consumption warnings. Or perhaps DebugWarning
if we want to put all kinds of debugging helpers in it.
Regards
Antoine.
